Specification of Letters Patent. Patented Aug. 29, 1 911.

Application filed July 21, 1910. Serial No. 578,027.

I that form of spectacles in W ich there are the blank employed protectivenose guards or pads on the nose bearing portions thereof;'and the objects of my improvements are first, to provide a bearing pad which does not employ independent means for attaching it to the uard, and second to provide a pad that can e made independently of any particular spectacle, but which can be furnished as a stock article of manufacture ready for application.

Another object of my invention is to provide a protective pad which can be readily removed and replaced by unskilled persons without the use of tools, so that the parts may be cleaned and accumulations of dirt, perspiration, etc.,' removed.

I attain these objects by the construction illustrated in the accompanying drawing in which;

Figure 1, represents a perspective View of a portion of a spectacle embodying my in vention. Fi -.--"2, represents a rear elevation of Fig.' 1;' ig. 3, represents the outward side of a spectacle bridge showing the means of connecting the pad thereto. Fig! 4, rep resents a section taken on the line 7-7 in Fig. 3. Fig. 5', represents a section taken on the line 88 in Fig. 3. Fig. 6, represents plate from which the guard is made.

Similar figures refer to similar parts throughout the several views.

Referring to the drawings Upon the under or concave side of the bridge 1 is attached a nose guard 2' which consists of a 1 plate 3 of substantially the same length as the concave side of the spectacle bridge and is preferably wider than the bridge.

The plate 3 is curved in the direction of its length to fit the concave under side of the bridge, as shown in Figs. 1 and 2. It

I may be also curved over the bridge in the direction of its width as shown in Fig. 4.

The edges 5 running in the direction of the length of the plate are turned up and in and given a permanent set by heating or other processes, as shown in Figs. 3 and 5, the distance between the upturned edges being less than the corresponding width of the bridge.

The plate 3 is preferably made of some suitable substance having sutficient elasticity to enable the upturned edges 5 ,to be sprung over the bridge and to retain it in place thereon, and capable of receiving a smooth 7 contact with the finish to fit it for continued nose, such as zylonite and similar materials, metals may also be used.

To place the guard on the bridge the upturned edges 5 of one end of the guard are pushed over the narrowest portion 6 of the bridge. The guard is then slipped along the bridge toward the opposite end until the upturned edges 5' first applied fit over and bind on the tapering edges of the bridge.

The remaining'upt'urned edges 5 not yet in contact are then pressed in until they spring over and engage the edges of the bridge. The guard 1s then slipped back until it reaches a central position on the bridge, the upturned edges 5, engaging the bridge edges after the manner of grooved slides; the

natural elasticity of the material causing the upturned edges to graspand hold the edges of the bridge with suflicient pressure to retain the guard in position.

. To remove the guard from the bridge the operation is the reverse from that described for placing it in place. The guard is slipped around toward one end or the other of the bridge, until the turned up edges 5 reach one of the narrow places 6 in the bridge, one end then is pulled out from the bridge, the guard is then slipped toward the other end of the bridge, leaving one pair of upturned edges 5 in contact with the bridge edges. When the narrow portion 6 at the opposite end of the bridge is reached the turned up edges can be drawn out from the bridge and the guard removed.-

It will be seen that-the guard requires no other fastem'n than the natural elastic ity of its material to hold it in place on the bridge and that it can be put on or taken off at will without the use of tools and by unskilled persons.

I 'am aware that prior to my invention guards have be 11 made for the bridges of spectacles. I, therefore, do not claim such a device broadly, but

What I claim as new and desire to cover by Letters Patent is:

1. A protective bearing ad for the nose bearing portions of spectac es and the like, fitting in and conforming substantially to the curvature of the nose bearing side of the bridge and adapted to retain its position relative to the bridge by means of the natural elasticity of the material from which the pad is made.

2. A protective bearing pad for the nose bearing portions of spectacles and the like, fitting in and conforming substantially to the curvature of the nose bearing side of the bridge and having its longest edges turned over the corresponding edges of the bridge, said edges retaining the pad in place.

3. A protective bearing pad for the nose bearing portions of spectacles and the l ke, fitting in and conforming substantially to the curvatures of the nose bearing side of the bridge and having its longest edges turned up and adapted to spring over and embrace the corresponding edges of the bridge, said upturned edges springing over the bridge and retaining the pad in position thereon by means of the natural spring or elasticity of the material from which the pad is made.

4. A protective bearing pad for the nose bearing portion of a spectacle bridge, fitting in and substantially conforming to the arch of the bridge and having the edges of its longest sides adjacent to the ends thereof turned up or curled, said turned up portions being adapted to spring over the edges of the bridge and retain the pad in place thereon by reason of the natural spring or elasticity of the material from which the padis made.

5. A protective pad for the nose bearing portion of a spectacle bridge, fitting in and substantially conforming to the arch of thc bridge the crown oflthe arch of said pad being wider than the corresponding portion of the bridge, and the edges of the longest sides diminishing from the crown toward the ends in both directions, a portion of said edges adjacent the ends of the pad being.

turned up and adapted to spring over the edges of the bridge by reason of the natural spring or elasticity of the pad material, and to hold the pad in place on the bridge.

6. A protective pad for the nose bearing portion of a spectacle or eyeglass, fitting in and conforming substantially to the curvature of the nose bearing side of the bridge and having elastic upturned edges adapted to spring over and grip the edges of the bridge.

In testimony whereof I affix my signature in presence of two Witnesses.
